Product Sample Applications

Sensor principle

The WxS9800 tilt sensing system uses gravity as its only stimulus, and a MEMS accelerometer as its sensing element. MEMS accelerometers typically employ a tiny, spring-loaded structure that is interlaced with a fixed pick-off finger structure. The spring constant of the floating structure determines how far it moves when subjected to a force. This structure responds to dynamic forces associated with acceleration and to static forces, such as gravity.
